Best Doom Eternal settings for the NVIDIA RTX 3090 Ti (2026)

On a NVIDIA RTX 3090 Ti (paired with a balanced Intel Core i9-12900F-class CPU), Doom Eternal runs at roughly 91 FPS at 4K with our optimized settings — up from about 92FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 3090 Ti is a high-end graphics card with 24GB of VRAM, and Doom Eternal is a moderately demanding game. Paired with the Intel Core i9-12900F, it runs great at 4K — about 91 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 227 FPS at 1080p and 160 FPS at 1440p, dropping to roughly 91 FPS at 4K. Its 24GB of VRAM is plenty for Doom Eternal, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

Recommended settings
Upscaling — DLSSOff
Doom Eternal (id Tech 7) added DLSS in a later update. The engine is famously well-optimised, so this is mostly a 4K / weaker-GPU lever.
Texture Pool SizeNightmare-1% FPS
How much VRAM is reserved for textures. Ultra is safe on 8GB; Nightmare wants 10GB+.
Lights QualityUltrabaseline
Number and quality of dynamic lights — the heaviest GPU setting in busy arenas. High/Ultra looks great without the Nightmare cost.
Shadows QualityUltrabaseline
Shadow resolution and filtering. Ultra is a clean step below Nightmare with barely a visual difference mid-fight.
Reflections QualityHighbaseline
Screen-space reflections on metal and blood. High is plenty during the carnage.
Volumetric QualityHighbaseline
Fog, smoke and god-rays. High keeps the mood while trimming a busy scene.
ParticlesHighbaseline
Gore, fire and explosion effects — lowering smooths the heaviest Slayer Gate fights.
